Japanese Cars That Don't Suck

by Mike Kojima

I pissed a lot of people off with my Japanese Cars Suck article a few weeks ago, where I expressed dismay at the boring state of the Japanese car industry. Japan Inc. seems to be producing either the uninspired transportation device or the trying too hard, over the top stuff that seems like something out of the Fast and the Furious or Transformers franchises.

Project EP3 Civic Si, Improving the Brakes with Fastbrakes, Stoptech and Willwood

by Mike Kojima

In the last edition of Project EP3 Civic Si, we explained how we went about converting our car from 4 lug to 5 lug hubs. We did this for two reasons: one to take advantage of the larger selection of 4x114.3 bolt circle wheels available on the market and to take advantage of the larger RSX Type-S wheel bearings and axles to stiffen up the bearing system in anticipation of performance fixed caliper brakes and more power from a possible engine swap.

Turbo Tech: Calculating Turbocharger Compressor and Turbine Performance Advantage with the New Honeywell Garrett GTX Gen2

by Khiem Dinh

In our Turbo Tech series, we have covered a lot of segments of turbocharger performance. We have looked at various aspects of compressor efficiency and performance, turbocharger mapping, and turbo sizing and matching among other things. This time around, we are going to do some more calculations on the turbine side, calculating pressure ratio and wastegate flow along with estimating power gains from the Honeywell Garrett GTX Gen2 turbos over the first generation GTX. You better get your Excel spreadsheets warmed up.

The Blackbird Fabworx Morpheus Miata!

by Mike Kojima

The cars created by Moti Almagor of Blackbird Fabworx have always caught our attention. More for less has always been the theme his creations. The Blackbird Fabworx cars have always eked amazing speed out of stock, very low powered engines. Lightweight, meticulous care in chassis setup, balanced brakes and carefully thought out aerodynamics have had a harmonious interplay in developing incredible speed from very little horsepower.

Testing Meguiar's Two Step Headlight Restoration Kit!

by Mike Kojima

Any car that has the newer plastic headlights will experience weathering and yellowing eventually. This is caused by UV light exposure degrading the protective coating on the surface of the lights. Once the coating is eroded, UV light makes quick work of the clear plastic underneath, and the light becomes cloudy and yellow.

How To Do A 5 Lug Conversion the Right Way! Project EP3

by Mike Kojima

As we finally start to mod our much-maligned shop EP3, the car that everyone loves to hate, we came to the realization that the car had pretty big wheel wells. To us, big wheel wells does not mean room for offset, slammed to the ground ride height or dumb camber but room for big grippy tires!

Testing Radium Engineering's Advanced Self-Draining Catch Can!

by Mike Kojima

Having proper crankcase ventilation is critical on a performance engine, especially forced induction ones that have more blowby past the rings by nature. The pressure needs to be relieved. Excessive crankcase pressure can blow seals, cause severe smoking from the turbo and affect piston ring seal causing smoking and losing power.

anti lag rocket beyond the dyno

External Combustion Rocket Anti Lag System + JDM Spec C Impreza STI

By Eric Hsu 

The external combustion anti-lag "rocket" combustor was used on the factory Prodrive built WRC STi Subaru cars to improve the EJ20 engine's inherent mediocre torque and engine response. The rocket is so good that a version of it is still in use today in the 2012 Japanese Super GT GT300 STi BRZ which also uses an EJ20. Last time I wrote a teaser article, but this time we'll take a look at some of the details of the rocket combustor anti-lag system as it applies to my buddy Ben's JDM Impreza STi Spec C street car over in the UK.

Tech Tip: How to Fix a Broken Mazda Door Handle

by David Zipf

It is important that we start off this Tech Tip be noting that it mostly applies to Mazda 3 owners, but also likely applies to 5 and 6 owners as well.  Mazda built the doors of all of these cars in a similar way.  If you own one of these vehicles (specifically the first generation from 2004-2010 or so depending on the model), you WILL have to deal with this problem at one point or another.  At some point your door handle WILL break, and you WILL have to replace it.  This will be a 100% failure rate over time and if you fix it early, it will make your life a bit easier.

Project E46 M3: Part 18 – Project M3 vs E90 M3 V8

by Pablo Mazlumian

We were pleased with our S54 3.2-liter in stock form, and the goal was to bring it up to V8 M3 performance. Was a 12% power improvement and 90-lb fat reduction enough? Find out inside! We test them to speed and in the quarter-mile. We also compare them from 30-100 MPH in third gear to compare low- and mid-range torque for you track guys! And why not--we even throw in a Mustang GT 5.0 in there...

10 Ways To Prepare Your Car For Spring And Summer

by Pablo Mazlumian

Most of us have a daily-driven vehicle that sees year-round driving. In an area where the temperature delta can exceed 100F in a given year, that starts to play a significant role in the vehicle’s wear and tear, as well as fuel economy. We’ve compiled 10 things to consider when readying your car for the upcoming warm season. Doing these things will not only ensure better fuel economy and overall performance, but increased life of the vehicle itself.

Project E46 M3: Part 17 – The preferred exhaust setup and more AEM tuning by MKC

by Pablo Mazlumian

Life would be a lot easier if we'd stayed with the stock headers, but when we tested our VAC headers in Part 3, the increase in power was too much to let go. Since then, we've tried different header-back systems but they either were too loud, droned at low RPM, or didn't fit all too well. Today, however, we think we've found something that works great and doesn't break the bank. Dynos graphs and video clips inside!

Subaru Clutch Forks Cracking Under Pressure?  Say It Isn’t So!

by Eric Hazen

Subarus have roamed the streets, tracks, and dirt for decades, with hundreds of thousands of upgrades available for nearly every aspect of these beloved cars.  Yet, one crucial part seemed to be passed over- the clutch fork! The clutch fork is Subaru’s Achilles heel. The clutch fork’s job is simple - disengage the clutch when you want to change gears. However, the stock part is prone to breakage and premature wearing of the pivot, especially when a performance clutch with higher clamping forces is used.

TESTED: Continental Tire ExtremeContact Sport

by Billy Johnson

“Same level dry performance as a Michelin Pilot Super Sport”. That is a HUGE statement by Continental when the PSS is hands down the segment leading benchmark.  Continental is extremely proud of their brand new ExtremeContact™ Sport tire that was just released earlier this month as a replacement for their ExtremeContact™ DW tire.  We logged nearly a thousand miles on the new Sport in both the wet and dry, and put it up against the outgoing DW in a back to back test at Palm Beach International Raceway to see if it lives up to Continental’s claims.

Project Viper GTS: Part 9 – RareFab/Roe Racing Oil Pan Baffle Kit

by Billy Johnson

Due to the high capabilities of the Viper, a huge strain is put on the factory oiling system on road courses and at the strip.  This can cause oil starvation and a spun rod bearing.  Using modern rubber can increase this risk, especially for 1996-1999 Gen-2 Vipers which have arguably the worst oil pan of any generation of Viper.  To combat this problem, we upgrade to the larger 10-quart oil pan and windage tray from the 2000-2002 Vipers and install RareFab/Roe Racing’s race-proven Oil Pan Baffle Kit.
